Benefits of technology

The patent text describes a method for allocating shared radio resources in a spectrum shared system (SSS). The method involves obtaining information about the radio service device and the node unit of the DAS, and determining whether the radio service device interoperates with the DAS based on the obtained information. The shared radio resources are then allocated to the radio service device and the DAS based on the determination of interoperation. The technical effect of this method is to enable efficient allocation of shared radio resources in the SSS and facilitate the use of the shared resources by the radio service device.

Problems solved by technology

However, a concrete method of controlling DAS and the spectrum sharing system has not been proposed yet.

Embodiment Construction

[0043]An example of a spectrum sharing system of the present disclosure is a new type of system in which two or more wireless communication systems provide authorized shared access in conjunction with an in-building wireless communication system (e.g., a distributed antenna system). Such a spectrum sharing system may be developed from a general CBRS system that provides or participates in authorized shared access between two or more wireless communication networks or two or more wireless communication systems (e.g., CBSDs or CBSD domain proxies).

[0044]As the spectrum sharing system of the present disclosure operates with the in-building wireless communication system, it is required to protect radio resources from each other based on constraints due to radio access technologies (RATs) being used by the in-building wireless communication system as well as RATs being used by general competing users or wireless communication systems. In addition, it is further required to protect radio ...

Abstract

The present disclosure provides a method of allocating shared radio resources in a spectrum shared system (SSS), the method including: obtaining, by a system controller of the SSS, identification information from at least one radio service device of the SSS and a node unit of a distributed antenna system (DAS); determining, by the system controller of the SSS, whether the at least one radio service device interoperates with the DAS based on the identification information; and allocating, by the system controller of the SSS, the shared radio resources to the at least one radio service device and the DAS, respectively, based on a result of the determining of interoperating.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This is a continuation of U.S. application Ser. No. 16 / 421,939 filed on May 24, 2019, which claims priority from Korean Patent Application No. 10-2018-0160328, filed on Dec. 12, 2018, and Korean Patent Application No. 10-2019-0024415, filed on Feb. 28, 2019, in the Korean Intellectual Property Office, the disclosures of which are incorporated herein in its entirety by reference.BACKGROUND1. Field[0002]One or more embodiments relate to a spectrum sharing system. More particularly, the disclosure relates to a method of operating a spectrum sharing system comprising a distributed antenna system.2. Description of the Related Art[0003]In order to cope with the increasing demand of mobile traffic and the limitation of frequency spectrum (or spectrum) retrieval and relocation, the introduction of radio station management and a service system based on spectrum sharing is being actively discussed in order to efficiently utilize limited radio resour...
